Observation of ψ (3686) →n n ̄ and improved measurement of ψ (3686) →p p ̄
(Amer Physic Soc., 2019)
We observe the process psi(3686) -> p (p) over bar eta' for the first time, with a statistical significance higher than 10 sigma, and measure the branching fraction of J/psi -> p (p) over bar eta' with an improved accuracy ...
Observation of J/Psi Electromagnetic Dalitz Decays to X(1835), X(2120), and X(2370)
(American Physical Society, 2022)
Using a sample of about 1010 J/ψ events collected at a center-of-mass energy s=3.097 GeV with the BESIII detector, the electromagnetic Dalitz decays J/ψ→e+e-π+π-η′, with η′→γπ+π- and η′→π+π-η, have been studied. The decay ...
